wnsnrne Mnonrnn- Application filed September 18, 1920. Serial No.411,040.

To all whom it may concern 7 Be it known that I, MAT EW J. BEAVER, acitizen of the United States, residing at Loyal, in the county of Clarkand State of Wisconsin, have invented certain new and usefulImprovements in Washing Machines,

of which the following is a specification. g The purpose of the presentinvention is. to provide an improved clothes Washing machine in which analternating rotary movement is given to the clothes rubber which, at thesame time, is automatically and vertically reciprocated upon the clotheswith a rubbing and beater action calculated to most efiectually cleansethe clothes dur ing the operation of the machine. e

An additional object is to provide an improved type of washing machinein which the rubber element is reciprocated through V the direct actionof a rotatable operating shaft and its crank portion without theinterposition of gears between the rubber and the shaft. v A furtherobject is to'provide awashing machine of simple and economicalconstruction', designed to be easily operated and capable of beingreadily taken apart for repairs or cleaning whenever desired. I With theabove andother objects in view,- the invention may be said generally toreside in the details of construction, combination and arrangement 'ofparts as will be hereinafter more fullyrpointed out, referencebeing hadto the accompanying drawings, whereini a Figure 1 is a top plan of amachine constructed in accordance with the invention.

Figure 2 is a vertical cross sectional'view taken on line 2 2 ofFigure'l.

Figure 3 is a similar View taken on the line 3-3 of Figure 2 anddisclosing the bend or crook forming the crank portio ofthe operatingshaft, and a 1 V "Figure 4 is a vertical longitudinal sectional view ofthe movable cross head of the rocker element.

a In the drawings, the numeral 1 represents a tub or other suitablewashing receptacle in which the clothes are deposited, such receptaclebeing adequately supported by suitable under supporting structure orlegs 2. The tub is provided'with a cover?) to one side of which a door4: is hingedly c011 nected. The cover and door fit into a socket orrecess formed upon the inner face of the tub sides and adjacent theupperedge as 7 indicated at 5. Access to the interior of the tub ispermittedonly through the opene ing of the hinged door, which however,may

be readily swung back when desired. A clothes rubber'is providedandconsists r V in a disk like head 6 havingaplurality of blunt projectionsor fingers 6" depending from the under face thereof, the head beingcarried by a stem or shaft 7 inserted through a guide opening 8 in thecenter of the cover and provided adjacent its upper end with anenlargement recessed to provide a seat or saddle 9 for the bow 10 of theoscillating rocker element. The bow or rocker 10 is mounted betweentheears-or flanges ll of the saddle andis pivotally re-t tained in place bymeans of a bolt or other 7 suitable fastener 12. When actuated thisrocker-is designed to tilt'from side to side for a purposetobehereinafter explained.. Arranged between theends of the rocker is across head or connecting member 13 I preferably cylindrical in crosssection and provided withan extension or laterally ofiset portion 14 asillustrated. A bore 15 extends centrally through the ofis et andtransversely across the member with respect to the longitudinal axis ofthe latter. At

its ends of thecross head is" provided with .85 c f socket-recesses 16for the reception 'of'pivot' I members 17 the latter being adjustably Vthreaded throughthe'ends of the rocker, i

- A pair of-supporting standards or brackets 18 are arranged-inalignment,- upon one side of'the central guide opening 8 of the coverand are secured to the latter asin dicated at19. These brackets areprovided at their uppermost ends with bearings 20 through'which theoperating shaft2lis'95 rotatably' inserted. Rigid with one end of theshaft is a large wheel 22 provided with a handle or grip23 by means ofwhich the wheels and shaft may be manually rotated. However,any othersuitable means may be employed for [rotating thesha'ftwhereby it mayj-beeitherv motor driven or-hand} operated. Crank means comprising a bend orloop 24 having angularly disposed side portions, one of whichiselong'ated as at 25, is formed integral. with the shaft and providesthe actuating means for the, oscillating rocker. The elongated end 25 isin sorted through the bore'1-5 of the movable cross head andis-of'smaller diameter than rotated about an axis from side to side andin a horizontal plane, thus tending to agitate or churn the hot, soapywater and stirring up the clothes to a sufficient degree. This isaccomplished by reason of the novel connection provided. between theshaft 7 and the operating shaft 21, and including the crank 24, therocker 10 and the cross head 13.

Assuming the parts, as illustrated in Figure 3, to be in neutral orstarting position, the rotation of shaft 21 correspondingly rotates thecrank portion 24 with the forwardly projecting inclined portion 25 ofthe crank describing a greater circle at its outer than at its innerend, governed of course, by the degree of inclination of the elongatedportion with respect to the perpendicular. Considering the shaft asbeing rotated in a clockwise direction the crank 24, in making the firstquarter turn will be brought to a horizontal position, the pivoted crosshead or roller 18 moving freely downward with portion 25 as the latteris turned to lie in the same horizontal plane with the shaft 21. It isto be noted from Figure 8 of the drawings that at the start the crankportion 25 extends transversely across the vertical axis of the crosshead 13 and at an angle thereto. Consequently, when the shaft is firstrotated the crank end will be shifted within the bore 15 of the crosshead so as to bind against diagonally opposite portions of the bore asindicated at X and Y respectively.

As the crank end is turned more and more from its Vertically uprightposition this binding action or pressure increases and since thepressure at X is on one side of the vertical axis of the shaft 7 androcker 10, tending to be exerted in one direction and the pressure at Yon the opposite side of the axis and exerted in an opposite direction,-

the tendency is for the rocker 10 to turn about its vertical axis untilit has assumed the position indicated by the dotted line structure ofFigure 1, with the crank lying in the horizontal plane and completingthe first quarter turn. Upon the continued rotation of the operatingshaft the pressure at X and Y will of course be respectively exertedupwardly and downwardly on opposite sides of the horizontal axis of thecross head 13 which being pivotally mounted is free to revolve, allowingthe crank to turn so that as the bend 24 moves upwardly the inclinedportion 25 moves downwardly, the

pressure at X and Y consequently shifting so that at Y it is exerted ina lateral direction tending to move the rocker around, while at X it isexerted in the opposite di rection, tending to swing the other end ofthe rocker around so that by the joint action or pressure at X and Y therocker and of course the clothes rubber, is swung back or returned toits original starting position, tl e pressure at X and Y continuallyshifting until at the completion of the second quarter or half turn theposition of the shaft, crank and cross head 13 will be completelyreversed. F or the third and last quarter turn, the operation is thesame as previously described with the exception that it occurs on thereverse side of the vertical axis, the binding action at X and Y turningthe rocker to the opposite side of that indicated by the dotted lines ofFigure 1, from which position it is returned at the completion of thelast quarter or full revolution of the shaft. It will thus be seen thatupon one complete turn or revolution of the shaft the rocker and clotheselement has been oscillated and toprevent any binding of the crankportion 25 andrthe cross head 13 which might, in any way affect theoperativeness of the device, the rocker 10 is permitted to rock fromside to side upon its pivot 11 as the shifting of the crank portionwithin the bore 15 of the cross head may require. It is further to benoted that as the crank revolves, the portion 25 is continually changingits position and as thecrank portion at Y moves up and around, it exertsa lifting force upon the cross head which causes the clothes rubber tobe vertically reciprocated through the guide opening 8, the openingtending to hold the clothes rubber steady and firm. The reciprocation ofthe clothes rubber will of course occur simultaneously with theoscillation of the shaft and rocker element, these movements beingrapidly effected upon the continuous rotation of the operating shaft.The movement of the clothes rubber is controlled entirely by the crankportion of the operating shaft and is governed according to the degreeof inclination given to the crank portion 25. No gears are required forthe transmission from the shaft to the clothes rubber and the lack ofgears in no Way detracts from the efficiency of the invention.

It is thought that the construction and operation of the machine will beapparent and clearly understood from theforegoing description taken inconnection with the drawings and it will be noted from the latter thatno extravagant or unnecessary parts are employed to burden the utilityor practicability of the invention. It is believed that the advantagesof the invention may be readily understood and appreciated from theabove disclosures which constitute but one form or application of theinvention, it being obvious that with changes and alterations of a minorcharacter the same may be readily adapted for and applied in various andother Ways.

Having thus described the invention'what I claim as new and desire tosecure by Letters Patent is r In a driving mechanism for a Washingmachine comprising a vertically disposed rotatable and reciprocatoryWork shaft, a substantially semi-circular yoke pivoted at its center tothe upper end of said Work shaft, a cross bar pivoted to the terminals,of said yoke, and a sleeve carried by the central the operating shaftand disposed at anangle 2 of substantially 45 degrees to thelongitudinal axis of said operating shaft and slidably mounted in saidsleeve.
